Ceftaroline fosamil

Experimental group

Description:

Patients will receive 600 mg of ceftaroline fosamil administered as a 120-minute intravenous infusion very 8 hours. Each dose will be infused in a volume of 250 mL over 120-minutes followed by aztreonam placebo in a volume of 100 mL infused over 30 minutes every 8 hours.
